The present document specifies technical characteristics and methods for measurements for satellite communications 
Earth Stations (ES) with the following characteristics: 
• The ES is designed for stationary operation. 
• The ES is operating as part of a satellite network (e.g. star, mesh or point to point) used for the distribution 
and/or exchange of information. 
• The transmit and receive frequencies are shown in Table 1. 
Table 1: Frequency bands 
Transmit (Earth-to-space) 1 
Frequency Bands/frequencies 
Transmit (Earth-to-space) 2 
27,5 GHz to 29,1 GHz  
29,5 GHz to 30,0 GHz 
Receive (space-to-Earth) 
17,3 GHz to 20,2 GHz 
• The ES transmits within the frequency range from 27,5 GHz to 29,1 GHz and 29,5 GHz to 30,0 GHz, which 
are bands allocated to the Fixed Satellite Services (FSS) (Earth-to-space) among other services. 
• At the national level, terminals covered by the present document, might operate on a co-frequency basis, with 
stations of other FSS networks / systems or with stations of other services. The present document does not 
cover requirements for ensuring protection of such services. 
• The ES receives within the range from 17,30 GHz to 20,20 GHz (FSS). 
• The ES uses linear or circular polarization. 
• The ES operates through non-geostationary satellites. 
• The ES is designed for unattended operation and it does not address specifications or requirements for earth 
stations operating as gateways or master earth station. 
• The ES is controlled and monitored by a Network Control Facility (NCF). This function may be performed 
centrally (e.g. for a network of ESs with a central hub) or it could be performed within the ES for autonomous 
control. The NCF is outside the scope of the present document. 
• The ES has one or more directive antennas that track satellites. 
The present document may also be applicable to the frequency bands 30,0 GHz to 31,0 GHz (Earth-to-space) and 
20,2 GHz to 21,2 GHz (space-to-Earth) subject to national regulation. 
The present document applies to the ES including its ancillary equipment and its various telecommunication ports, and 
when operated within the boundary limits of the operational environmental profile as defined by the intended use of the 
ES 
NOTE: The relationship between the present document and essential requirements of article 3.2 of Directive 
2014/53/EU [i.1] is given in annex A.

The present document specifies vulnerability handling activities, technical requirements and corresponding assessment 
criteria for routers, modems intended for connection to the internet, and switches related to cybersecurity. The products 
with digital elements in scope: 
• are specified within the "technical description" of the "category of product" in Class I, point 12 by the 
Commission Implementing Regulation (EU) 2025/2392 [i.2] of 28 November 2025 on the technical 
description of the categories of important and critical products with digital elements pursuant to 
Regulation (EU) 2024/2847 of the European Parliament and of the Council [i.1] as: - - - 
"Routers are products with digital elements that establish and control the flow of data between different 
networks by selecting paths or routes using routing protocol mechanisms and algorithms, typically 
operating at the network layer. 
This category includes but is not limited to wired and wireless routers, virtual routers and routers with or 
without modems."; 
"Modems intended for the connection to the Internet are hardware products with digital elements that use 
digital modulation and demodulation techniques to convert analogue signals from and to digital signals 
for IP-based communication. 
This category includes but is not limited to fibre modems, Digital Subscriber Line (DSL) modems, cable 
(DOCSIS) modems, satellite modems and cellular modems."; 
"Switches are products with digital elements that provide connectivity between networked devices 
through traffic forwarding mechanisms typically implemented at the data link layer. 
This category includes but is not limited to managed switches, smart switches, multilayer switches, 
virtual security switches, programmable switches for software-defined networking and bridges such as 
wireless access points."; 
• are only covered within the product context described in clause 4. 
The present document covers those products to demonstrate compliance with the essential cybersecurity requirements 
of Regulation (EU) 2024/2847 [i.1], Annex I Part I, under the conditions identified in Annex A. 
NOTE 1: The term "internet" refers to any public network accessible beyond organizational boundaries. Public 
networks are accessible to multiple organizations or the general public. Private networks operate under 
single organizational control. 
Routers, modems intended for connection to the internet, and switches fall within the scope of the present document 
when they provide management capabilities. This applies to all deployment forms such as dedicated hardware, virtual 
machines, containerized applications, and cloud-native network functions. The intended purpose or reasonably 
foreseeable use is to process, forward, or manage network traffic between devices, network segments, or between public 
and private networks. 
NOTE 2: Unmanaged products with fixed functionality and no configuration interface are excluded from scope, as 
they lack the interfaces needed to implement the security controls of the present document. 
The present document does not specify protocol conformance requirements, performance specifications, QoS metrics, 
or interoperability testing. Security controls for protocol implementation and vulnerability management remain within 
scope. 
NOTE 3: Products that integrate particular wireless or wired communication technologies, such as Wi-Fi®, cellular, 
DECT, and DECT-2020 NR remain within scope when they function as routers, modems intended for 
connection to the internet, or switches 
Routers, modems intended for connection to the internet, and switches intended for use in the industrial Operational 
Technology (OT) domain are excluded from the scope of the present document, see prEN 50770-5 [i.14].

The present document specifies test severities and methods for the verification of the required resistibility of equipment 
according to the relevant environmental class. 
The tests in the present document apply to stationary use of equipment at weatherprotected locations covering the 
environmental conditions stated in ETSI EN 300 019-1-3 [1].
